Use Las Leñas as your starting point when comparing accommodation in Mendoza. Check the official operator’s piste map, lift status and transfer arrangements before choosing your base.
July–September is an indicative winter travel window for this destination. It is not an opening calendar or a snow guarantee. Check the resort’s own updates before committing to dates.
Ski above the lakes of northern Patagonia or travel south to Tierra del Fuego. Distances are substantial, so plan these as distinct trips.
Before setting off, compare the wind and the temperatures at the forecast point with the elevations you plan to ski. New snowfall in the forecast and snow depth on a piste describe different things. The operator’s latest lift and piste report is the place to check what is open.
The forecast point is at about 2,256 m (Copernicus DEM / Open-Meteo terrain estimate).
For a nearby comparison, Malarguee is about 58 km away in a straight line. Check both forecasts if your plans include these places. The distance is measured in a straight line, not along the road.
Around the June solstice, there are approximately 9h 50m of daylight, compared with 14h 30m at the December solstice. These are astronomical estimates, not sunshine forecasts; cloud and the local horizon affect the light you see.
Compare seasons in the weather history. Check the selected period, source and data coverage: station observations and gridded historical estimates describe different records.
Distances are approximate and measured in a straight line. Nearby places may not have a direct road, piste or lift connection.

For Las Leñas a comparable total piste length has not been verified from the sources checked. A missing value does not mean there are no pistes. Destination information.
Local, linked and regional totals overlap and must not be added. Run counts and terrain in acres are different measures from piste length in km.

Start with the 14-day weather forecast. Open the detailed tables to compare models, then explore hourly temperature, precipitation, wind and 850 hPa in the meteogram. Ensembles show the spread of possible outcomes; satellite images show observed clouds.
Available model families combine per variable. “Today” with hours in parentheses covers the stated window; subsequent days require full local coverage. Days 8–14 are less certain; missing data remain blank. Snowfall cm are fresh snow, not snow depth. Sea-level pressure. Terrain temperature downscaling by Open-Meteo; no Agios Stefanos calibration.

Satellite images and rain radarThis summary uses the destination’s fixed coordinates and the historical service’s terrain elevation. It does not change with the forecast’s manual elevation setting. Mountain terrain, wind redistribution and snowmaking are not fully represented. Snowfall days do not indicate opening days or piste snow depth.
Explore rain and snowfall frequency, monthly average daily lows and highs, and daily temperature extremes over the selected period.

Choose 10, 20 or 30 years of temperature and precipitation history. The 100-year option searches for a nearby NOAA station with a sufficiently long record; the table shows the actual coverage. NASA POWER / MERRA-2 and ERA5 provide gridded historical estimates, while NOAA GHCNd contains station observations. These sources are shown separately, not combined into one time series.
A precipitation day has at least 1 mm of total precipitation. Where a source reports rain separately, the rain-day figure covers rain alone. A snowfall day has at least 0.1 cm of fresh snow where that variable is available; it does not establish snow cover on the ground. NASA POWER does not provide snowfall here. Blank values mean missing data, not zero. Averages and extremes use only the complete months or years stated in the table. These historical figures do not automatically calibrate the forecast.

Global Spectral Model: the Japan Meteorological Agency’s global numerical weather model.
Artificial intelligence ensemble with 31 members. It complements the single AIGFS forecast with alternative scenarios and their spread.
The blend uses the values available for each day and variable. Coverage falls as individual models reach their forecast limits. The two IFS products are not independent models. Model spread shows disagreement, not the probability of a weather event.
Wind: maximum daily speed at 10 m and prevailing direction of origin. Direction uses a speed-weighted circular calculation; missing or strongly opposing directions display a dash. 🥶: low below 0°C. 🥵: high above 30°C. 💨 in Conditions: wind at least 40 km/h or gusts at least 60 km/h.

The choice applies to widgets, maps and forecasts. Actual station readings stay unchanged. Automatic tries Open-Meteo first, then available direct sources if a supported request fails.
Data service providing forecasts from NOAA, ECMWF, ECCC, DWD, the Met Office, Météo-France and JMA. Available models, variables and grids depend on the location and product.
XIONIA collects data directly from the model providers. Forecasts and maps are served after the source cycle has been published and collected. The selected product shows its model, resolution, available variables and run.
Each available family contributes once per variable. Direct forecasts select the freshest available GFS grid and use equal family weights as the baseline. Local weights apply only where enabled after validation. The comparison shows actual percentages and model cycles.
Additional model forecasts are also shown for comparison and backtesting. Their presence does not automatically add weight to the combined forecast; check the displayed weights.
A dash means unavailable data. Wind and gust may use different models. AIGFS temperature is excluded when it cannot be compared on the same elevation basis. Six-hour precipitation is water equivalent, not snow depth.
A “Today” label with hours in parentheses covers only the stated time window; subsequent days require full local coverage. Days 8–14 are a less certain outlook. Agreement between models is not a probability from a true ensemble.
Ensemble systems provide multiple forecast scenarios; the available systems appear in the chart selector and image catalogue. AIGFS is the single forecast; AIGEFS is the separate ensemble. Available variables and forecast horizons differ by system.

The forecast point for Las Leñas is at 2,256 m (Mendoza · -35.1480°, -70.0830°).
Use the daily forecast to compare fresh snow, temperature and wind. The mountain view shows the selected day and model; XIONIA’s combined forecast is selected initially. Fresh snowfall and snow already on the ground are separate measurements. Snowfall elevation is a model value or a labelled approximate estimate when available. Days 8–14 show a less certain trend.
The forecast refers to this point; conditions on the summit and at the ski base can differ. Check the resort operator for lift and piste status.
